What does place interlocking markers on both ends of this row mean in knitting?

Placing interlocking markers on both ends of a row in knitting serves as a way to denote the beginning and end of a specific section or repeat within a pattern. This helps knitters keep track of their progress and ensures they maintain the correct stitch count. It can also aid in identifying where to make increases, decreases, or other pattern changes. Overall, it's a useful technique for maintaining organization and accuracy in complex knitting projects.
